When it comes to cold storage, is your first thought: “Is it cold enough?”
But here’s the thing—a healthy cold room is more important than just low temperatures!

If door seals are worn out, evaporators are buried in frost, or condensers are clogged with dust... you're not just losing cold air—you’re burning up to 30% more electricity, risking equipment failures, product loss, and even safety hazards!

At Guangdong ARTECO, we believe cold room maintenance should be part of every boss’s money-saving playbook. Regular defrosting, pipe cleaning, sensor calibration—these may sound like chores, but they extend equipment life and save you a cold room’s worth of repair costs every year!

Daily Details That Matter

1. Door Seals: Keep the Cold In

Follow proper opening procedures: Always open and close the cold room door quickly. Leaving it open causes major temperature swings.

Monthly seal inspection: Check rubber strips for cracks, hardening, or warping. Replace them at the first sign of damage.

Seal upgrades: Install extra rubber strips or brushes on the door’s inner frame to block gaps. Clean them regularly to keep them elastic.

2. Defrosting: Frost = Hidden Power Thief

Air-cooled rooms: Frost thicker than 5mm? Time to defrost! Efficiency drops up to 30% if you don’t.

Drain care: Clear melted water right after defrosting to avoid refreeze blockages.

Auto-defrost checkup: Inspect timers and heating elements regularly for proper operation.

3. Stacking Goods: Give Your Cold Room Space to Breathe

Golden rule: Keep at least 10cm from the wall, 30cm from the ceiling, and spacing between products.

Don’t block air vents! Poor airflow = uneven cooling + surprise frost.

Regular Checkups = Long-Term Savings

1. Cooling System: Like a Heart, It Needs TLC

Compressor sounds: Weird noises? Might be low oil or internal wear.

Condenser & evaporator: Dust and grease kill heat exchange. Clean monthly!

Dry filter: Check every 6 months—if it clogs, expect high-pressure alarms.

2. Electrical Safety: Prevent Fires Before They Start

Stable voltage: Fluctuations over ±10% can shorten compressor lifespan.

Aging wires: Inspect relays and contactors. Burn marks? Replace them ASAP!

3. Insulation Layer: Your Cold Room’s Armor

Wall checks: External condensation or internal warping? Fix immediately.

Floor insulation: Damage here can cause icy floors—and double your repair bill.

A well-maintained cold room runs more efficiently, lasts longer, and breaks down less often.
